Contact lens cleaner for cleaning stylus cartridge ?

My suggestion and opinion....

Check with the cartridge manufacturer to find out their recommendations for cleaning their stylus. Most use some kind of adhesive to attach the stylus to the cantilever. The last thing you want to do is to use or do ANYTHING that loosen that attachment or cause the stylus to become detached.

Contact cleaner is probably a benign solution, but why take any chance at all?

In considering the OP’s question, doesn’t contact lens cleaner contain a bit of lubricant? Wouldn’t that potentially form a film on the cantilever and stylus that could pick up more contaminants?
